"Semi-autonomous" means partly self-governing: the organelle has some genetic machinery of its own but is not completely independent of the cell's nucleus.
Look at each option:
- Carrying out photosynthesis is a functional role, not a reason for genetic autonomy.
- Being membrane-bound is true of many organelles (mitochondria, vacuoles, etc.) and has nothing to do with genetic independence. …
